Answer:
SEE BELOW
Step-by-step explanation:
1 - 12000 ft
2 - 10 minutes
3 - The third segment in he graph is not as steep as the first segment because the flight took more time to lose altitude than the time taken to gain altitude.

Answer:
Part a)
Part b)
Step-by-step explanation:
we know that
The scale is
That means
2.4 cm in the model represent 1 foot in the real
Part a) we know that
The restaurant is 20 feet tall
Find the height of the model
Multiply the actual height of the restaurant by the scale 2.4
A bottle cap is 1.2 cm tall
To find out the number of bottle caps divide the height of the model by 1.2
Part b) we know that
A popsicle stick is 15.2 cm tall
To find out the number of popsicle sticks divide the height of the model by 15.2
Convert to mixed number
Answer:
t =5
Step-by-step explanation:
2-16t=6(-3t+2)
Distribute
2-16t = -18t +12
Add 18t to each side
2-16t+18t = -18t+18t +12
2 +2t = 12
Subtract 2 from each side
2-2 +2t = 12-2
2t =10
Divide each side by 2
2t/2 =10/2
t =5
Answer:
Step-by-step explanation:
<h3>Question 1</h3>
V and W are midpoints of RU and ST ⇒ VW is a midsegment
VW = 1/2(RS + UT) ⇒ RS = 2*VW - UT
<u>Substitute values:</u>
- 2x + 15 = 2(2x + 5) - (6x - 37)
- 2x + 15 = 4x + 10 - 6x + 37
- 2x + 15 = -2x + 47
- 2x + 2x = 37 - 15
- 4x = 22
- x = 5.5
RS = 2x + 15 = 2(5.5) + 15 = 11 + 15 = 26
Question 2
- Trapezoid given with congruent sides, JM = KL
- Angle J and K are congruent, both are (7x + 2)
- Angles M and L are congruent, both are (2x - 14)
<u>J and M are supplementary, so sum to 180°</u>
- 7x + 2 + 25x - 14 = 180
- 32x = 192
- x = 192/32
- x = 6

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?
The recursive formula for this geometric sequence is:
= 2; = (-5) •
Step-by-step explanation:
To find the recursive formula for a geometric sequence:
- Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
- Find the common ratio. (The number you multiply or divide.)
- Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
The recursive formula is:
= first term; = r • , where
- is the first term in the sequence
- is the term before the nth term
- r is the common ratio
∵ The geometric sequence is 2 , -10 , 50 , -250
∴ = 2
- To find r divide the 2nd term by the first term
∵
∴
- Substitute the values of and r in the formula above
∴ = 2; = (-5) •
The recursive formula for this geometric sequence is:
= 2; = (-5) •
